LapTAP Trial Summary

Randomized, Double-Blinded, Placebo-Controlled Trial of Laparoscopic Transverse Abdominis Plane (Lap TAP) and Rectus Sheath Block in elective Gastric Bypass Surgery aiming to evaluate the benefit of a laparoscopically -guided, surgical transversus abdominis plane (TAP) block and rectus sheath block in reducing post-operative opioid consumption and improving outcomes in patients undergoing laparoscopic gastric bypass surgery. The results of this study will provide further evidence on the optimal means to obtain analgesia in patients undergoing gastric bypass surgery

LapTAP Trial Design

2Treatment groups
Experimental Treatment
Placebo Group
Group I: TAP and Rectus Sheath ropivacaineExperimental Treatment1 Intervention
The block will be administered in the anterior abdominal wall. For the TAP block, the standard technique will be followed- at the anterior axillary line midway between the subcostal margin and iliac crest. For the rectus sheath block, a bilateral sub-xiphoid approach will be used. There will be 4 injection sites in total and the size of the needle will be standardized to an 18g spinal needle 10cms. Using laparoscopic visualization, the transversus abdominis muscles were identified lateral to the semilunar line. Ropivacaine to be infiltrated will be divided into 4 equal amounts. The procedure is then repeated 2 times in the transversus abdominis plane (20mL each) and 2 times as a Rectus Sheath Block (10mL each) with a total amount of 60 mL.
Group II: TAP and Rectus Sheath Normal SalinePlacebo Group1 Intervention
TAP and Rectus Sheath Block of 60 mL Normal Saline divided into 4 injections administered as in Experimental Arm.
